I'm in Israel right now, staying in the Armenian quarter of the Old
City of Jerusalem, and I noticed something odd, afaik, about a couple
satellite dishes I see on a couple buildings.

The dishes are about 3 to 4 feet wide, iiac, and there is a rod across
the front that holds an "antenna" in the focal point, I guess, of the
concave dish.

But there are also 2 more antennas, one on the left of center and one
on the right, about 8 to 10 inches away from center. All three are
white boxes about 3 inches x 3 x 4. I can understand why they might
need three antennas, but I don't see how 2 of them can be so far from
the center. Maybe they're not using the other two, just storing them
for when the center one breaks? ??

They are using three feedhorns to pick up three different satellites
at the same time. This is a prime focus configuration, and a scaled
down version of the 'Simulsat' concept.
